In this work we revisit ZZ UMa to determine its physical properties to high precision. We base our analysis on the RVs from Lacy & Sabby [1]} and Imbert [2]}, and on light curves from TESS. A detailed scientific motivation is presented in Paper I of this series [3]} and a review of the use of space-based photometry for the study of binary systems is given in Ref. [4]}.
